Chart displays in the Info menu (outdoor temperature fluctuation and solar yield) The Info menu gives you the option of viewing graphs showing the fluctuation in outdoor temperature over the past two days and (if solar components are installed) the solar gyield. This way you have a clear overview allowing easy comparison of the relevant values. Both graphs are updated every 15 minutes and a new graph is started at 12:00 am (00:00) (midnight). Consequently, there will be no display available for the current day between 12:00 am and 12:14 am (00:00 and 00:14). The minimum and maximum values are updated progressively. Outdoor temperature curve (weather station) The temperature variation over the current and previous day is shown across two screens. The minimum and maximum values since midnight on the previous day are also shown. Solar yield 1) The solar yield display tells you how much the solar collector has contributed to domestic hot water heating. This is determined using the difference in temperature between the storage tank and the solar collector, together with the modulation of the solar pump. The solar yield is highly dependent on the installed system and its components and therefore cannot be expressed as a value in kWh. This means that the value displayed is a variable specific to this particular system, which cannot be easily compared with other solar heating systems. However it is suitable for comparing the yield on different days. This information is displayed as a graph for the previous and current day. The solar gain per day and also the weekly total is listed in a table: SOLAR YIELD THIS WEEK and also for the previous week: SOLAR YIELD LAST WEEK. In both cases the current day is indicated by a flashing dot. This value is updated every 15 minutes (also in the graph for the “current day”) and the total is saved at 12:00 h (midnight) as the value for the relevant day. The daily values for the current week (Mo-Su) are also added up every 15 minutes. The days in the current week which still have not passed are marked with “---”. At days where the solar yield could not be determined “0” is displayed.

What is a heating zone? A heating zone describes the route taken by the heating water from the boiler to the radiators and back to the boiler. Multiple heating zones can be connected to one boiler; for example, one heating zone for panel radiators or baseboard and another heating zone for radiant floor heating. In this case, the radiators are supplied at a higher supply temperature than the radiant floor heating system. The supply temperature is the heating water temperature, generated by the boiler, as it is supplied to the heating zone. With the RC35 user interface, you can operate and control multiple heating zones (Æ Fig. 2).

5.5.2 Modes of operation for DHW You can set one of the following operating modes for your hot water supply: • automatic (program) This can be either the program for central heating or a specific DHW program (Æ page 39). • permanent ON (manual continuous mode). The hot water is permanently maintained at the set temperature. • permanent OFF (manual night mode). You can use the button to start DHW heating when needed (“Heating up DHW once”, Æ page 19). 5.5.3 Operating modes for DHW circulation1) The DHW recirculation pump ensures quick supply of hot water to the taps (if installed). This is achieved by circulating the hot water once or more per hour through the DHW recirculation pump via a separate recirculation pipeline. The recirculation interval (the number of times per hour) can be adjusted by your heating contractor in the Service menu. You can set one of the following operating modes for DHW circulation: • automatic: 30 minutes before the first heating zone is switched on, the DHW recirculation pump starts to run at the set interval, and stops when the last heating zone is switched off (factory setting). Alternatively, you can set a separate circulation program (Æ page 39). • permanent ON: The DHW recirculation pump runs constantly at the set interval, regardless of the heating zones. • permanent OFF: The DHW recirculation pump is not run at a set interval. You can use the button to heat up the DHW and start DHW circulation when needed. 5.5.4 Operating modes for solar • automatic (default setting) • permanent OFF (manually switched off) • permanent ON (manual constant operation). The solar heating system will be in constant operation for 30 minutes at maximum pump output. After 30 minutes the solar heating system automatically switches back to automatic mode. The solar pump is controlled manually in “constant operation” operating mode; however, the solar heating system will cut out if either the collector array or the solar tank exceed their maximum permissible temperature (collector protection function). For explanations of the settings, see the documentation for the solar module.

5.6 Setting the program The automatic mode ensures automatic switchover between day and night mode at defined times of day. In the factory setting, 70 °F (21 °C) is set for day mode, and 63 °F (17 °C) for night mode. Before you select a program (i.e. a heating program), consider the following: • At what time in the morning should your home be warm? Does this time vary depending on the day of the week? • Are there days when you do not need your home to be heated during the day? • From what time in the evening does your home no longer need to be heated? This too may vary depending on the day of the week. 1. Open the User menu. 2. Select program. 3. If your heating system is equipped with more than one heating zone (Æ page 26): select the desired heating zone and confirm. A separate program can be set for each heating zone. You will then see the following options to choose from: – select program (Æ page 32) – show current prog. (Æ page 35) – change switch point (Æ page 35) – enter switch point (Æ page 36) – delete switch point (Æ page 37) – room temperatures (Æ page 38, not possible for DHW, DHW circulation and solar heating zones) 4. Recommended: Use the select program option to select the program which best corresponds to your lifestyle. 5. If the standard program needs to be adjusted: change, insert or delete individual switch points. -or6. If you want to create a completely new program: select program and set a new program. The enter switch point menu item (Æ page 36) opens automatically for you to create your program. In the factory setting, the program also determines the times for DHW heating and the operation of the DHW i.e. circulation pump. However, you can also set separate programs for both functions (Æ sections 5.7 and 5.8).

5.6.6 Setting room temperatures The room temperatures menu item is only available for heating zones without a remote control unit (the first case below). In the other two cases, the room temperatures menu item is not displayed. Possible case scenarios: • Heating zones without remote control (Æ page 54, setting “none”): different room temperatures are possible for each zone, in contrast to the RC35 heating zones. The room temperature is set as described below. • RC35 heating zones: the room temperatures are the same for all heating zones assigned to the RC35. For the RC35 heating zones, you need to set the room temperature using the button, not in the User menu (Æ page 16). If “shut-down mode” is selected as the night setback mode, the heating system will be switched OFF at night. A night room temperature cannot be set. The display will show a message to that effect.

5.7 Setting a DHW program In the setting by heating zone (factory setting), the switch-ON and switch-OFF times for hot water heating follow those of the selected program. This ensures that hot water is available during the heating phases (i.e. when in day mode). If you want to enter a separate hot water program, Buderus recommends: • Heating the hot water tank only once in the morning before home heating starts. • Possibly also programming another heating phase in the evening if more hot water is regularly needed at that time. This would allow you to significantly reduce your energy consumption even further. To set a hot water program that is independent of the heating phases: 1. Open the User menu. 2. Select program. 3. Select the domestic hot water heating zone. 4. Adjust the program with change switch point, enter switch point or delete switch point (Æ page 35) or enter a new program. 5. Save the program as custom 1 or select not saved to cancel. 6. Check that automatic is set for operating mode\DHW to make sure that the program you have set is also active (Æ page 30). If you occasionally need more hot water outside the set time, you can activate hot water heating for a short time (“Heating up DHW once”, Æ page 19).
5.8 Setting the DHW circulation program1) You can use a DHW circulation program to enter the switch-ON and switch-OFF times for the DHW recirculation pump independently of the program for the heating system. Follow the same procedure as for entering a DHW program (Æ section 5.7).
1) This function depends on the boiler in use.

5.9 Setting the warm weather shutdown (WWSD) temperature Requirements: An outdoor temperature sensor must be installed. The heating system is controlled by the outdoor temperature (with or without influence from room temperature: Æ page 47). In the case of room temperature control, the WWSD temperature menu is not displayed. When the outdoor temperature falls below this adjustable threshold, the heating system automatically switches over to winter mode (heating on). Make sure that the automatic mode is active. 1. Open the User menu. 2. Select WWSD temperature. 3. If your heating system is equipped with more than one heating zone (Æ page 26): select the desired heating zone and confirm. 4. To save energy in spring and autumn: lower the switchover threshold (factory setting: 63 °F (17 °C)). 5. To heat your home more comfortably in spring and autumn: increase the switchover threshold. If you occasionally feel too warm or too cold, you can also make use of the manual mode (Æ page 14).
The heat storage capability of the building is also taken into consideration and utilized during the switchover. Since the temperature in your home falls gradually, you may find that the heating system does not switch over to winter mode until some time after the outdoor temperature has dropped below the switchover threshold.
5.10 Setting the daylight savings time changeover There is no automatic summer/winter time change. Adjust the time as shown on page 17.
5.11 Set the DHW temperature The domestic hot water (DHW) temperature is the target water temperature in the hot water storage tank. WARNING: Risk of scalding! The factory setting for DHW temperature is 140 °F (60 °C). There is a risk of scalding at the taps if no thermostatic mixing valve is installed. B Make sure that a thermostatic mixing valve is installed and that it is set to temperatures below 122 °F (50 °C).

5.16 Calibrating the room temperature display If there is a separate thermometer near the RC35 when installed in the living space, it may show a different room temperature to that shown on the unit. If you wish to adjust the RC35 to match the thermometer (i.e. “calibrate” the RC35) , you can use the corrected room tmp. function. Before calibrating the room temperature, consider the following: • Is the thermometer more accurate than the RC35? • Is the thermometer located close to the RC35 so that they are both subject to the same heat influences (e.g. sunlight, fireplace)?
1) The function depends on the boiler in use.

Information for setting the RC35
6.1 Control modes for the heating system The heating system has three different control modes. Your heating contractor will select one according to your requirements and will set it up for you: • Outdoor temperature control (weather-dependent control): the outdoor temperature is recorded by means of a temperature sensor. The level of the supply temperature is calculated solely on the basis of the outdoor temperature in accordance with the characteristic heating curve. You can set the room temperature for the entire home on the controls (which will push the heating characteristic curve up or down). If you have the thermostatic radiator valves installed, adjust them in every room so that the desired temperature is reached in each room. • Room temperature control: in this case, the RC35 must be mounted in a room that is representative of your home. The RC35 records the room temperature in this “reference room”. Control of the supply temperature is determined by the set room temperature and the recorded room temperature. This means that external temperature influences in the reference room (e.g. an open window, sunlight or heat from a fireplace) can have an effect on the entire home. Set the room temperature for the home/reference room on the RC35. You can produce higher or lower temperatures in the other rooms by adjusting the thermostatic radiator valves (if installed) or flow balancing valves. • Outdoor temperature control influenced by room temperature: With this control mode the supply temperature is primarily determined by the outdoor temperature, but it is also partly determined by the room temperature, to an extent set by your heating contractor. For room temperature control and for outdoor temperature control influenced by room temperature: If installed, the thermostatic radiator valves in the “reference room” (the room where the RC35 is mounted) must be completely open. Control of the supply temperature is determined by the room temperature recorded there. It must never be limited by closed thermostatic values.

6.2 Tips for energy efficiency • You can save around 6 % on your heating costs by reducing the daytime room temperature by 2 °F (1 °C). • Only heat if you need warmth. Use the program for automatic night setback. • Ventilate your home wisely: Leave the windows wide open for a few minutes rather than leaving them slightly open all the time. • While ventilating rooms, set the RC35 to night mode. Do this by pressing the night button. • Have drafty windows and doors sealed or replaced. • Never position large objects such as a sofa immediately in front of radiators or baseboard (maintain a clearance of at least 20" (50 cm)). Otherwise, the heated air cannot circulate and heat the room adequately. • You can also increase the energy efficiency of your hot water supply: compare the times when you want your rooms to be warm with the times when you need hot water. It may be practical to use a separate program for DHW heating. • Arrange with your local heating contractor to have your heating system serviced annually. A clean and properly adjusted boiler uses fuel most efficiently and promotes a longer service life.

Troubleshooting
This chapter contains frequently asked questions about your heating system and their answers. This will in many cases enable you to troubleshoot perceived faults. At the end of the chapter there is a table listing faults and corresponding remedies.
7.1 Frequently asked questions Why do I need to set a room temperature even though it is not recorded? When you set a room temperature – even if room temperature is not recorded, as is the case when heating is controlled by outdoor temperature – you are changing the characteristic heating curve. That changes the room temperature, because the temperature of the boiler water changes and with it the temperature of the radiators, baseboard or radiant floor heating.
Why does a separate thermometer not match the room temperature set in the RC35? Various different factors influence the room temperature. If the RC35 is installed on a cold wall, it will be influenced by the cold temperature of that wall. Conversely, it will be influenced by the heat from a fireplace or chimney, if it is installed in a warm part of the room. If you would like to compare the recorded room temperature with the measurement values of another thermometer, the following is important: • The separate thermometer and the user interface must be physically close to each other. • The thermometer must be accurate. • When comparing, do not measure the room temperature when the heating system is in the process of heating up, as the two devices may react at different speeds to the change in room temperature. If you have followed these instructions and you can still detect a discrepancy, you can now calibrate the room temperature display (Æ page 45).
Why do the radiators get (too) hot although the outdoor temperature is relatively high? If you have a heating system with a heating zone and no mixing valve (heating zone 1), this is normal. The pump only starts up when the boiler reaches a predefined supply temperature. If the supply temperature is higher than required based on the outdoor temperature, the radiators may get hotter for a short time. The heating control detects this and responds accordingly after a short time. Do not adjust the thermostatic valves if installed on the radiators or the room temperature on the RC35, and wait until the set room temperature is reached. Even in summer mode, the radiators may be heated for a short time under specific circumstances: namely when the pump is started up automatically at a predefined interval, to prevent it from “seizing up” (jamming). If the pump happens to be started up immediately after DHW heating, the unusable residual heat is dissipated via the heating zone and the radiators.

Troubleshooting
Why does the pump run at night, even though the home is not being heated at all or only very little? This depends on the setting chosen by your heating contractor for night setback. • setback mode: even when the home is only being heated a little, the pump runs in order to achieve the set room temperature, even if low. • shut-down mode: the heating system (and therefore also the pump) is automatically shut down in night mode. If the outdoor temperature drops below the frost protection temperature, the pump is automatically switched on by the “Frost protection” function. • Outdoor setback mode and Room setback mode: The heating system is switched on automatically when the recorded temperature falls below the set value. The heating pump runs:
The recorded room temperature is higher than the set room temperature. Why is the boiler running anyway? The boiler may be heating the domestic hot water. The heating system has three different control modes (Æ page 47): • Room temperature control: the boiler shuts down when the set room temperature has been reached. • Outdoor temperature control: the heating system runs on the basis of the outdoor temperature. • Outdoor temperature control influenced by room temperature: the heating system uses the advantages of both of the above control modes. In the last two cases the boiler may run even if the recorded room temperature is higher than the set room temperature.
